問題描述

我想通過 Web 服務更改遠程清單，我知道通過 Event Observer Method 可以觸發我的代碼，但我不知道哪個事件對完成我的任務有用，例如 on_order_complete，是否有更新的列表事件或更多文檔?

I want to change via web service a remote inventory, I know that via Event Observer Method can triger my code, but I don't know which event is useful to complete my task, like on_order_complete, is there an updated list of events or more documentation?

如果您想在訂單狀態更改為任何狀態或狀態時分派事件，則需要插入自己的事件偵聽器.這并不像聽起來那么難.

If you want to dispatch an event when the state of an order changes to any status or state, then you'll need to insert your own event listener. This isn't as difficult as it sounds.

只需像這樣覆蓋Mage_Sales_Model_Order中的_setStatus函數...

Simply override the _setStatus function in Mage_Sales_Model_Order like so...

/**
 * Order model
 *
 * @category    WMG
 * @package     WMG_Sales
 * @author      Lee Bolding <lee.bolding@wmg.com>
 *
 *  Supported events:
 *  sales_order_status_before
 *  sales_order_status_after
 *
 * NOTE: Unfortunately, we can't override setState() as the protected _setState()
 * function is used by the registerCancellation() and _checkState() functions
 *  
 */
class WMG_Sales_Model_Order extends Mage_Sales_Model_Order
{
    /**
     * Order state protected setter.
     * By default allows to set any state. Can also update status to default or specified value
     * Сomplete and closed states are encapsulated intentionally, see the _checkState()
     *
     * @param string $state
     * @param string|bool $status
     * @param string $comment
     * @param bool $isCustomerNotified
     * @param $shouldProtectState
     * @return Mage_Sales_Model_Order
     */
    protected function _setState($state, $status = false, $comment = '', $isCustomerNotified = null, $shouldProtectState = false)
    {
        // dispatch an event before we attempt to do anything
        Mage::dispatchEvent('sales_order_status_before', array('order' => $this, 'state' => $state, 'status' => $status, 'comment' => $comment, 'isCustomerNotified' => $isCustomerNotified, 'shouldProtectState' => $shouldProtectState));

        // attempt to set the specified state
        if ($shouldProtectState) {
            if ($this->isStateProtected($state)) {
                Mage::throwException(Mage::helper('sales')->__('The Order State "%s" must not be set manually.', $state));
            }
        }
        $this->setData('state', $state);

        // add status history
        if ($status) {
            if ($status === true) {
                $status = $this->getConfig()->getStateDefaultStatus($state);
            }
            $this->setStatus($status);
            $history = $this->addStatusHistoryComment($comment, false); // no sense to set $status again
            $history->setIsCustomerNotified($isCustomerNotified); // for backwards compatibility
        }

        // dispatch an event after status has changed
        Mage::dispatchEvent('sales_order_status_after', array('order' => $this, 'state' => $state, 'status' => $status, 'comment' => $comment, 'isCustomerNotified' => $isCustomerNotified, 'shouldProtectState' => $shouldProtectState));

        return $this;
    }
}

您現在可以為觀察者訂閱新創建的 sales_order_status_before 和 sales_order_status_after 事件

You can now subscribe observers to the newly created sales_order_status_before and sales_order_status_after events
